I really enjoyed Sony's conference last year as unlike previous years, they really focused on showing gameplay footage. They still had to push developments at Sony pictures for some reason but overall the conference was a big improvement over 2013's one.
I still didn't bother to watch Microsoft's conference last year but the Master Chief Collection got me super hype and Cuphead looked interesting.
Ubisofts's was total crap though. Most of the stuff shown was just cutscenes or extremely long teasers that seemed more like they belonged at a TV and movie convention, rather than a gaming expo. Even more annoying is that they keep having a second (and much better conference) during Sony's presentation. Seriously, just the opening cutscene of Far Cry 4 in your own and then 30 minutes of actual gameplay in Sony's? Still, it beat the hour Assassin's Creed had at Sony's 2013 press conference.
